MOSES LAKE — Gilbert Lee Williamson, the alleged driver in the attempted murder of Moses Lake resident Dale Olmos, was arrested Sunday morning at a Moses Lake home.

Authorities have been searching for Williamson, 46, since Dec. 11, when Olmos, 28, was found in rural Moses Lake with a gunshot wound to the head. Prosecutors charged Williamson in Grant County Superior Court with first-degree rendering criminal assistance.

Williamson allegedly drove Olmos and three other people, including Jordan Wiester, 21, and Jose Rivera, 16, to a field near Hiawatha Road and Road 5 Northeast where Wiester allegedly shot Olmos. Wiester and Rivera were charged with first-degree attempted murder.

Just after midnight Sunday, Moses Lake police received an anonymous tip that Williamson was at a home in the 300 block of North Earl Road. Officers located Williamson inside the home and he was arrested without incident.

Williamson also had a district court warrant for failing to appear for third-degree possession of stolen property and two Adams County warrants for failing to appear for a financial review hearing.
